[Updated] Windows Phone 8++ Registry Hacks

This is a recompilation of registry hacks for Interop-unlocked Windows Phone devices.
I have tested this on my freshly hard-resetted Lumia 730; Windows Phone 8.1 GDR1.
I have used CustomPFD to explore the whole WP Registry, I will update this thread if I find something new and unusual.

- Created registry values are tested while there are some that says create a key for this key, I did not include it without initial and further testing
- Most WPTweaker tweaks are not here though, I still haven't consulted them for replicating their list of tweaks. All of the tweaks below are the ones I always use/alter on my device.
- Several tweaks might still apply on W10M but I haven't tested it out yet.
